Making Geographical Comparison
Part One - Constructing Overlays to Build Knowledge
- Find and download maps showing electoral ridings, major municipalities, time zones and other information that you would like to see in Google Maps. (A good starting point is The Atlas of Canada - http://atlas.gc.ca/site/index.html)
- Use the zoom tool to move closer or further away from an area where the map that you found will fit over Google Earth.
- Add an “Image Overlay” on Google Earth by selecting the pushpin button and choosing “Image Overlay” from the menu.
- Give your image overlay a “Name” and “Description”, then “Browse” to the map that you had previously downloaded.
- You can change the transparency of the map by moving the slider to the left or right.
- You will need to adjust the location of the map to align it with Google Earth. By grabbing the green handles around the map you can resize the map.
- If you select the cross in the middle of the map you can drag the map around the earth. If you select the diamond shaped handle you can rotate the map.
- When you are done select the OK button.
Students could be asked to do critical thinking tasks: Identify commonalities between overlays? IE. electoral ridings, major municipalities of Canada, and time zones that determine the closing of electoral polls.
